Vessel Positional Data Transmission Rule Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vessel tracking systems face inefficiencies in communicating positional data, leading to redundant data transmission and increased bandwidth usage, which is costly and wasteful, especially when multiple vessels within overlapping communication ranges report the same data.
Innovation Solution
Implementing a management system that generates and communicates transmission rules to vessels to control the reporting of positional data, reducing redundant data transmission by determining which vessels should report data from overlapping areas, using methods like coverage scoring and simulated annealing to optimize wireless signal coverage and minimize duplicate data communication.

Engineering Contradiction Analysis
1Reliability
If all vessels within communication range report positional data to the management system, then comprehensive vessel tracking is achieved, but redundant data transmission increases bandwidth usage and costs
Solution Approach 1:
The system segments the vessel fleet into different reporting groups based on their communication coverage areas. Vessels are divided into segments where only certain representative vessels report data for specific geographic areas, eliminating redundant reports from vessels in overlapping coverage zones while maintaining comprehensive tracking coverage.
Solution Approach 2:
Instead of requiring all vessels to report positional data (excessive action), the system implements partial reporting where only selected vessels within communication ranges are required to transmit data. This partial action is sufficient to achieve comprehensive tracking without the waste of redundant transmissions from all vessels.
2Loss of energy
If transmission rules are implemented to reduce redundant data communication, then bandwidth usage decreases, but system complexity increases due to rule generation and distribution
Solution Approach 1:
Vessels autonomously determine their own reporting requirements by receiving communication range information from the management system and independently identifying which vessels fall within their coverage area. Each vessel self-adjusts its reporting behavior based on the transmitted rules without requiring complex centralized control or intervention.
Solution Approach 2:
The management system transmits communication range information and positional data to vessels, which then use this feedback to determine their reporting obligations. The system continuously updates transmission rules based on vessel positions and communication ranges, creating a dynamic feedback loop that optimizes data transmission without excessive complexity.

AI summary
Vessel communications systems and methods are described. According to one aspect, a vessel communications method includes receiving a first inbound wireless communication within a subject vessel, the first inbound wireless communication comprising positional data regarding a location of a first vessel, receiving a second inbound wireless communication within the subject vessel, the second inbound wireless communication comprising positional data regarding a location of a second vessel, selecting the positional data of the first vessel but not the positional data of the second vessel and after the selecting, outputting an outbound wireless communication comprising the positional data of the first vessel but not the positional data of the second vessel.
